DOUBLE-ACTING PUMP.

SPECIFICATION forming part of Letters Patent No. 323,398, dated August1885,

Application filed May 22, 1885.

To all whom it may concern:

Be it known that LDANIEL R.CLOUD, a citizen of the United States,residing at Detroit, in the county of lVayne and State of Michi gan,have invented certain new and useful Illl provements in Double-ActingPumps; and I do declare the following to be a full,clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings,and to the letters and figures of referencemarked thereon, which form a part of this specification.

The nature of my invention in double-acting pumps relates to theemployment of valves in duplicate working horizontally with valves induplicate working vertically, with but one plunger, said valves andplunger working in cells formed integral with the body of the pump incasting, the object being to produce a strong, positive, and easyactingpump at a nominal cost; and my invention consists in the arrangement ofparts, as hereinafter set forth, and pointed out in the claims.

In the drawings formingapart of this specification, Figure 1 is anisometrical perspective view of my device in elevation. Fig. 2 is asection in elevation on dotted lines 2 2 of Fig. 4. Fig. 3 is alongitudinal section in elevation on dotted line 1 1 of Fig. 4. Fig. 4is a top plan having head and valves removed. Figs. 5 and 6 areisometrical perspective views of the valves, as will be hereinafterfully set forth.

A. represents the body of the pump, which is formed in one part, havingthe valve-chamhers B B B B, the ledges Z Z and d d, the partitionE,having valve-openings t t, and the supply-openings z z,leading fromthe valve-chambers B B to'the cylinder 0 of the pump. All of theforegoing parts are formed integrally with the body of the pump. To thefront of said body I attach the supply or suction pipe F, leading intothe central chamber,D, located between the valve-chambers B B, as shownin Fig. 2.

At the bottom of the central chamber I locate a vent-cock, O, andleading from the bottom of the lower valve-chamber, B, is a dripcock,0-. The valves K have a valve-stem, a. Said valves are seated in acircular base, I),

(No model.)

having valve-openingf. Said cicular base is screw-threaded at e, and isscrewed into the internally-threaded ledges d d, as shown in Figs. 2 and3. The yokcs Y are formed integral with the bases b, havingescrow-threaded hole at 6, into which I screw the thimble h, having thescrew-threaded head d (See Figs. 2 and 6.) The valve-stem (4 passeswithin the thimble 7c, the free end pressing against the coiled spring8, housed within said thimble, as shown in Figs. 2 and 3. The degree ofpress ure upon the valves K is obtained by adjusting the thirnbles itwithin the yokes Y by turning the head (1. Said valves are located in avertical position, one over the other,with the supply or suction pipelocated between them leading into the central chamber, D, as clearlyshown in Fig. 2. The valves H are provided with thimbles 12., fittingover the thimbles 0, containing the coiled springs g, which is common.The thimbles o are formed integral with the base,having the arms on.Anchored to said arms are guides or supportingpins Said pins are locatedin a horizontal position within the valve-chests B B, as shown in Fig.

'3, the arms on meeting the ledgesl I, which support them, the free endsof the pins iineeting the wall or face of the partition E,whereby saidvalves are held in position opposite the ports t t. (See Fig. 3.)

The discharge-pipe R is located over the upper valve-chamber, B,receiving the water as it is forced through the valve-openings t t. Saidpipe is attached to the top plate or head, N, of the pump. Said head isprovided with an annular flange, D, which fits snugly within the barrelor cylinder 0 of the pump, being out out at z" in front of the port 5,as shown in Fig. 2. Said plate extends Over the valvechambers B B, asshown in Figs. 2 and 3. The bottom head or plate, N, is formed with alike annular flange, D, fitting into the lower end of the cylinder 0, asshown clearly in Figs. 2 and 4, being also cut out at 12 in front of thelower port, z. The head also passes over the lower valve-chambers, B B.Said plate is provided with ears W; also the upper plate, and throughthe holes a the bolts 8 pass, thus securing the heads to the pump-body.

. P is the piston head or plunger working in the cylinder 0, and 'l isthe piston-rod working through the stuflingbox B Pivoted to the upperend of the piston-rod is a coupling-rod, L, the upper end of which ispivoted to the car 71- of the handleplate M. Said plate is pivoted atthe center to the cap C, mounted upon the upright pipe or fulcrumsupportE. Said support is located at the side of the pump, and is anchored tothe curbplank W, as shownin Fig. 1. The handle plate is hollow, and isadapted to receive the handles h, by which the piston-head is driven.

In Fig. 1 I show a four-way coupling, S, mounted upon the discharge-pipeR, having the stand-pipe D", with cap 9 and vent-cock 2, thus forming anair-chamber. Attached to the horizontal openings of the coupling S areelbow-couplings o v. To the outer elbows I attach reducers w .90.Between the elbows at the right hand I locate the cutoff plug t Whensaid plug stands open, and the hose-pipe is detached, I have twodischarges. WVhen the hose-pipe H is coupled, as shown in Fig.

1, and the water is cut off from the right-hand discharge by the plugit", the water is all forced through the hose, having full pressure ofthe pump, enabling me to throw a strong stream.

I attach to the upright F, by means of a bolt, 1), the reel R, forsupporting the hose ready for use.

In pumping the movements of the parts are as follows: As the piston-headP of Fig. 2 is drawn up by the action of the handle h, the valve K inthe lower chamber, B, opens, as shown in Fig. 2, the valve K over itcloses, as shown in said view, when the water in the cylinder over thepiston-head is forced out through the upper port 2, closing the uppervertical valve, passing through the valveopening t, forcing back theupper horizontal valve H in chamber B, as shown in Fig. 3, the waterflowing into the outlet B. As the lower valve K drops, a vacuum isformed in chamber D, thus drawing water through the supply-pipe F intosaid chamber, through the Valve-openings f into the bottom of thecylinder, through the lower port 2, following the piston-head in itsupward movement, the lower horizontal valve closing the lower valveopening t as the lower vertical valve opens the port f. As thepiston-plunger descends the upper horizontal valve closes the upper portt. The upper vertical valve rises at the same time the lower verticalvalve closes the port f. The pressure of the water forces back thelowerhorizontal valve, opening thclower port t, the water under thepiston-head being forced out into the chamber leading to thedischargepipe. At the same time the water is drawn through thesupply-pipe F, as indicated by the upper arrow ofFig. 2, through theupper ports,

fand' z, filling the cylinder over the pistonhead.

It will be observed from the foregoing, to each movement of thepiston-head there is a movementofall ofthe valves; that the piston-headin its ascending and descending lifts and forces the water, thusthrowing acontinuous stream.

The opening of the vent-cock G admits air into the chamber D, when thewater in said chamber returns through the supply-pipe into the Well toprevent freezing. Opening the drip-cock O carries the water out of thebottom of the pump.

Having thus fully set forth my present invention, what I claim as new,and desire to secure by Letters Patent, is-

1. In a pump, substantially as specified, the combination of the bodycontaining the barrel (J, the valve-chambers and ledges, with chamber D,the partition E, having ports it, the
